You may have followed this story on Twitter during the past fortnight, which focused on Usain Bolt being appointed Nissan’s new “Director of Excitement”, along with news of a one-off gold GT-R and a special ‘Bolt GT-R’ which will go into limited production in 2013.

Infiniti is offering a rare chance to get behind the scenes at the Red Bull Racing factory in Milton Keynes as the car maker celebrates the crowning of Sebastian Vettel as double Formula One World Champion. And for the true enthusiast and FX owner, Infiniti has introduced a specially commissioned wrap for the car inspired by the Red Bull Racing livery.

With Malaysian-born Tony Fernandes as its new owner, it was only a matter of time before Caterham Cars set up a permanent residence in India – you see, despite being born in Kuala Lumpur, the Air Asia and Team Lotus boss’ late father was Indian.

Remember the RX-8? It seems a long while since we heard from Mazda’s rotary-engine four-door, four-seat sports coupe, but it’s still on sale and the Japanese market is receiving a final special edition version called the RX-8 SPIRIT R.

Nissan seem to be following in the foot-steps of their arch nemesis, Porsche, with a range of GT-R versions to mark the 2011 model year. Granted, there’s still a long way to go before they catch up with the 26 variants of 911, but if it works for ze Germans, then why not for Japan’s most revered sports car maker.

So it’s unoffical (and Nissan have no plans on making one), but it’s such a credible adaptation of the iconic GT-R that we just had to take notice. An estate version of the GT-R?, sounds like a good idea..
